- PATENT OFFICE.

BUTTON-FASTENER.

SPECIFICATION forming part of Letters Patent No. 241,518, dated May 1'7,1881.

Application filed February 18, 1881.

To all whom it may concern Be it known that 1, WILLIAMHENRY Srnos- TON,of Birmingham, in the county of Warwick, in that part of the UnitedKingdom of Great Britain and Ireland called England, have inventedcertain new and useful Improvements on Button-Fasteners; and I do herebydeclare that the following is a full, clear, and exact description ofthe same.

The object of this invention is to produce a fastener which can beapplied to hold a button without clamping the fastener to the leather orfabric, and the button be attached and detached with facility withoutdestroying the fastener; and it consists of a metallic fastener stampedout of sheet metal, as hereinafter described, and consisting of asuitably-formed head with central prongs having hookedterminationsfacing in opposite directions laterally to one another, whereby, whenthe prongs are passed through the material and the shank of a button isinserted between the prongs and slightly turned, the shank will passinto the hooks and become fastened by the prongs closing laterallytogether by pulling the button, the head of fastener preventing itspassage through the material to which the button is to be secured.

Figure l is a plan view of my improved button-fastener as cut from thesheet metal. Fig. 2 is a side view of the same bent into form. Fig. 3 isa transverse view of the same with button attached.

A is the head portion or back of the fastener, which may be either flat,or concavo-convex, or cruciform, or of other suitable shape.

B B are prongs integral with the head A, and have hook-shapedterminations G C bent in opposite directions or. toward one another,whereby when laterally together the hooks form a central hole, whichconfines the shank of the button when inserted, as hereinafter described.

(No model.) Patented in England August 23, 1880.

In forming the fastener the prongs are bent over the head A until theymeet, and are then bent laterally together. The portions bent laterallypass through the leather or fabric, which is pierced by a stiletto orother instrument. When the head A is against the back of the leather orfabric the hooked portions of the prongs project from its face, the headA preventing their through passage.

In the drawings, Fig. 1, the head A is shown as a disk, with the prongsB B projecting from opposite diameters with terminal hooks O C, allintegrally stamped out of sheet metal and bent to the form shown in theother figures.

The button is attached to the fastener by in sertin g its shank betweenthe prongs B B, and by a quarter-turn of the button the shank will passunder the hooks G G, and escape will be prevented by a strain on thebutton closing the hooks laterally together.

To remove the button, the hooks are spread laterally and the shankturned in alignment therewith, when, being free from the books, a pullon the buttonwill part the hooks laterally and detach the button.

I claim as my invention- As an improved article of manufacture, thebutton-fastener herein described, consisting of the disk or head A andprongs B B, integrally stamped out of sheet metal, said prongsprojecting from opposite sides of the disk or head and havingoppositely-bent hook-shaped ter minations O O, substantially as andforthe purpose set forth.
